- runtime/i18n.ts: ICU-lite messages (placeholders as text, Intl.PluralRules plurals with exact
forms, selectordinal, select, number/date/time), fallback chains (pt-BR -> pt -> en, ar-x-fm ->
ar), X and legacy code aliases, RTL by locale, lazy catalogs, live onChange. Apostrophes are
literal except right before { } # or another apostrophe.
- runtime/i18nCheck.ts: rules for contributed catalogs (shape, keys, syntax, placeholder parity,
select options, markup/control characters, lengths). An argument English only uses to choose a
plural form may be dropped; missing plural forms are warnings; meta "allowEmpty" fragments.
- runtime/pluginI18n.ts: api.i18n bound per plugin (register/t/locale/dir/onChange/number/date/
relative/list); the UI kit's own words follow the app's language. pageLang.ts reports the
site's <html lang>. shell/messages.ts: shell-model words.
- waybetter-host i18n.rs: NativeStrings (validated plain text, caps, one-pass {name} fill, page
payload by prefix), system_locales via sys-locale; TabState.lang.
- JSON Schemas for catalogs and translator notes; npm exports waybetter/i18n, /i18n/check,
/i18n/plugin.
layout.rs (headless, tested): Placements remembers each tab webview's last rectangle and
visibility, so a tabs_sync that changes nothing makes no native call and one that moves one
pane touches one webview; Frame/follow_rect estimate where panes go when the window size
changes (outer margins fixed, proportional in between, shared borders stay shared).
host.rs: place_tab/forget_tab use it; place_child is a single set_bounds (one WebView2
SetBounds instead of a move then a resize, each a page re-layout); follow_window_resizes
re-places visible tabs from the window's own Resized events on the main thread, before the
shell lays out again, and keeps WindowMetrics current so a sync needs no blocking round
trips for the window size; layout_window says when a layout was made for a stale size.
Linux: the shell becomes a GtkOverlay layer itself (an empty box is the base) and is
re-ordered to the top or bottom of the overlay; a tab placed while it is raised goes under
it. macOS: the shell's WKWebView is re-ordered among its superview's subviews
(addSubview:positioned:relativeTo:), keeping the first responder if it was in the shell.
Both now report support, so overlays no longer hide the tabs there either (the app makes the
shell webview transparent; macOS needs tauri's macos-private-api).
Windows: a tab webview about to be hidden hands the shell its last frame (WebView2
CapturePreview, JPEG, `tab-still` event), for its pane to show instead of an outline while
no webview is on screen there.
- host plugins.rs: PERMISSIONS, parse_permissions, ScriptPlugin.permissions/problems (None = legacy,
full API), validate_plugin (file name, 2 MiB, UTF-8 text without binary bytes, header with @name
and @version, valid @permissions, network:none refused when the code calls network APIs),
source_findings, PluginStore::install (atomic rename, never enables, keeps the enabled state on
update) / remove / is_enabled / file_hash. start/stop scripts run the module body, construction,
start() and stop() inside window.<global>.withPlugin(id, grants, fn) when the runtime has it.
- runtime permissions.ts: parsePermissions, scopePluginApi (undeclared gated members throw a
PluginPermissionError; scope().ui gated like api.ui), createPluginContext (the view of the plugin
whose code runs; legacy = full API). A declaration and guard rail, not a sandbox.
- The `commands` permission name comes from the parallel palette-commands work (its API lands there).
tao's thread event target and the single-instance message window are visible
1 px unowned top-level windows. taskkill /PID (WM_CLOSE, no /F) closes only the
first such window in z-order; a minimized app window sinks below them, so the
close destroyed a helper and the app kept running. route_helper_closes
subclasses those helpers and forwards WM_CLOSE to the app window.
- plugin: *.plugin.js with the store header and start/stop on api.scope, storage, observe,
onKey, the UI kit (toast with action, ui.h settings dialog) and api.theme/--wb-* vars;
--ts makes a TypeScript project typed by the waybetter package (build keeps the header first)
- theme: JSON with "$schema" -> theme.schema.json, palette derived like themeFromColors,
font roles (family, tweet), presets
- app: Tauri 2 + waybetter-host + runtime + shell models: SiteSpec, SiteAdapter, shell/tab-chrome/
site-tab capabilities, tabs_sync, plugin store, a site-only command; presets for youtube.com,
kick.com, twitch.tv with placeholder selectors; host crate via submodule, path or git
- tests generate into temp dirs: headers via parse_meta (new plugin_meta example), plugin code
against createCorePluginApi's members, themes against the schema, app TS with tsc against the
built package, app Rust with cargo metadata/check/test
- wired into bun run check (typecheck incl. checkJs, build:packages, test:create) and pack:check
tauri 2 (runtime-wry build_gtk with the window's GtkBox) packs every child
webview into the window box, stacked and with set_position/set_size ignored,
so tab webviews landed under the shell instead of over their panes.
place_child/attach_shell move them into a GtkOverlay (shell as base layer)
and allocate each at its exact rect via get-child-position; placed_rect
reports the placement (GTK children have no position). Windows/macOS keep
set_position/set_size.
set_tab_visible shows/hides a tab webview and sets
ICoreWebView2_19::SetMemoryUsageTargetLevel (LOW when hidden, NORMAL when
shown). Hidden tabs keep running; the browser trims their working set.
Site-agnostic parts of the X app, behind a small site adapter:
- crates/waybetter-host: webview-label security policy and tab rect
clamp, account profiles with native-owned accounts (AccountRules),
plugin store with bundled-plugin upgrades (PluginHost), signed
data-only hotfix channel, update scheduling and crash handshake, tab
payloads/link routing/tab-chrome validation, and (feature "tauri")
webview helpers and the Windows system menu.
- packages/runtime: DOM hub, request hub, plugin API core, OKLab theme
color model, split-view rail hiding, link routing and account
reporting, each configured by a SiteAdapter.
- packages/shell: address bar, pane, link-drop, profile, palette and
update-chip models, and window controls with the Tauri API injected.
Tests moved/adapted from the app: 45 Rust (headless), 40 TypeScript.
